Fluidizing unit for a powder conveyor and powder conveyor with fluidizing unit

Abstract

The fluidizing unit for a powder conveyor has a powder suctioning opening, a powder suctioning canal and a fluidizing ring, which is arranged above the powder suctioning opening and concentrically to the powder suctioning canal. Moreover the fluidizing unit has fixing means, which are developed in a way that they hold the fluidizing ring such that the outer surface area of the fluidizing ring remains at least partially free.
